King James Bible
"And be ready against the third day: for the third day the LORD will come down in the sight of all the people upon mount Sinai."
God commands the Israelites to prepare themselves for a divine encounter, emphasizing the need for ritual purification and consecration. The three-day preparation period mirrors other biblical instances where this timeframe marks significant spiritual transitions. This announces an unprecedented theophany—God himself will descend from heaven to earth. The phrase underscores both the certainty and the extraordinary nature of this divine visitation at a specific, appointed time. Unlike private revelations to individuals, this manifestation will be public and verifiable, establishing the covenant before the entire nation as witnesses. Mount Sinai becomes the sacred meeting place between heaven and earth, where God will reveal his law to Israel.
